Answer: (2a+2b,2c)
the first one
Step-by-step explanation:
you can add or subtract letter such as *a or *b so you "add" them which is 2a+2b and "y" for point B is 2c so it stays the same
sorry i such at explaining
1/5 pound would be 20% of a pound or 0.2 pounds :)
Multiply both sides by 12 to get a = 240
8/12= 4/6 = 2/3 hope this helps! thank you!
